Claims.

The present invention relates to improvements in door stops, and hasparticular reference to a stop that is adapted for holding a door inopen position.

In making repairs on an automobile and servicing various parts thereof,such as the instrument board, transmission, battery, etc., it is quitedesirable that the door of the automobile be maintained in openposition, thus allowing the mechanic to gain access more easily to thedifferent parts.

It is proposed in this connection to provide a stop, which may bereadilyapplied in place for holding the automobile door open. It will,of course, be understood that my door stop is not to be limited to thisparticular use, and I will describe the stop with reference to anautomobile door merely by way of illustration.

-An object of my invention is to provide a door stop, which is adaptedto be fastened to one of the door hinges in such a manner that the stopwill hold the door against closing until such time as the stop has beenremoved.

A further object resides in the provision of a door stop that will allowfurther opening of the door from an initial open position. The stop ismade for automatically extending itself when the door-opening is widenedso as to maintain contact with the door.

A still further object is to provide a door stop that will automaticallylock itself against return movement in any position to which it may beextended.

Moreover, I propose to provide a door stop 35 adapted to be applied tothe hinges on either side of the automobile or the like, and which willbe firmly anchored in position after being attached thereto.

Other objects and advantages will appear as the specification proceeds,and the novel fea- 1937, Serial No. 166,993

Although I have shown only the preferred form of my invention, it shouldbe understood that various changes, or modifications may be made withinthe scope of the claims hereto annexed without departing from the spiritof my invention. 5

Referring to the drawing in detail, I have illustrated a body post Ihaving a door 2 secured thereto by means of a hinge 3 in the usualmanner. The hinge comprises two straps 4 and 5., Which are journalled ona vertical pin, as at 6'. It will be understood that when the door isclosed the faces 6 and I of the body post I and the door 2,respectively, contact one another. Figure 1 shows the door after it hasbeen opened to a position at right angles to the side 8 of theautomobile.

My door stop is indicated generally at 9 in the several views, andincludes in its structural features a substantially T-shaped body memberID, having the arms ll of the T slotted, as at l2, for engagement overthe hinge strap 4.

The stem I4 of the T-shaped body member extends through the space, whichis defined between the body post and the door when the latter is opened,and in Figure 1 the stem is substantially parallel with the automobileside 8. The free end of the stem [4 has a squared opening I5 formedtransversely therein for slidably receiving a rod I6, the latter alsobeing square in cross-section. It will be understood that the opening I5and rod "5 may be round, if desired.

In Figures 1 and 4, I show the rod It as having an enlarged head H,which is urged away from the stem M by means of a spring l8 workingbetween the stem and the head. The latter abuts the face 1 of the doorin the manner shown in Figure 1 in normal operation. Upon opening thedoor wider, the head is maintained in contact with the door by means ofthe spring I8, and the latter at all times prevents the stop fromaccidentally becoming disengaged from the hinge strap 4.

For holding the rod I6 against return movement in any position to whichit may be extended, 1 form ratchet teeth l9 along the length of the rod,which are engaged by the pawl 20, (see Figure 4). The pawl is urged intothe space between the teeth by means of a spring 2| interposed betweenthe squared head 22 of the 50 pawl and a sleeve 23, the latter beingthreaded into the end of the stem l4.

A handle 24 may be manually retracted for disengaging the pawl from theratchet teeth and thus allow the head IT to move toward the stem I4. Thehead 22 of the pawl may be guided in a squared guideway 22', if desired.

The rod It extends laterally from the stem at right angles with respectto the arms ll of the T, and a nut 25 limits the movement of the head I!away from the stem.

Having thus described the various parts of my invention, the operationof the door stop may be readily understood. The door 2 is first openedinto substantially the position it occupies in Figure 1. The spring 18is then compressed by moving the head I! toward the stem 14, and

the stop is placed in position by engaging one of the slots l2 over thehinge strap 4, (see Figures 1 and 2), with the head I! abutting the faceof the door.

It is apparent that upon opening the door 2 further the head I! ismaintained in contact with the door by means of the spring 18. The rod[6 moves to the right in Figure 1 as the door opening is widened, andthe ratchet teeth l9 are free to move beneath the pawl 20. However therod is held against return movement from any extended position by meansof the pawl, unless the latter is first released by manually retractingthe handle 24.

When the door stop is applied to the righthand door of the automobile,with the hinge arranged at the front of the door, the slot I2 is engagedover the hinge strap 4'. Upon applying the stop to the left-hand door,with a similar hinge arrangement, the stop is turned upside down and theslot I2" is used for anchoring the stop to the hinge strap.

I claim:

1. A door stop comprising a body member having means for anchoring themember to a hinge strap, and means on the member for abutting a door forholding the latter against closing, said last-named means beingextensible when the door is opened wider, and means for automaticallyextending the door-abutting means when the door-opening is widened so asto maintain contact with the door.

2. A door stop comprising a body member having means for anchoring themember to a hinge strap, and means on the member for abutting a door forholding the latter against closing, said last-named means beingextensible when the door is opened wider, and means for automaticallyextending the door-abutting means when the door-opening is widened so asto maintain contact with the door, and means for automatically lockingthe door-abutting means in any position to which it may have beenextended.

3. A door stop comprising a body member having means for securing themember to a hinge strap, and a rod adjustable transversely in the memberand arranged for abutting a door for holding the latter against closing,the rod having ratchet teeth thereon, and a pawl engaging the ratchetteeth for locking the rod against return movement after the rod has beenextended fromthe member.

4. A door stop comprising a body member having means for securing themember to a hinge strap, a rod adjustable transversely in the member andhaving an enlarged head thereon arranged for abutting a door for holdingthe latter against closing, and a spring working between the member andthe head for automatically maintaining the latter in contact with thedoor as the door-opening is widened.

5. A door stop comprising a T-shaped body member having slots in thearms of the T for receiving a hinge strap, a rod slidable transverselyin the stem of the T at right angles to the arms thereof and arranged toabut a door for holding the latter open, and yielding means urging therod against the door.
